Albert Augustus Trever, A History of Greek Economic Thought
“ The physiocrats thought that commerce and industry increased the value of raw materials only enough to pay for labor and capital expended. Commerce was an expensive necessity, a tax on agriculture. For a good summary, cf. Haney, pp. 138 ff. Quesnay (Tableau Econ. [1776] ) followed Xenophon (Econ. v. 17) as his motto. But the motive of the physiocrats was economic, not moral and political, as was that of Aristotle. ”
